PCV Valve: What Is It?

Posted November 29, 2016 10:44 AM

Most Anchorage drivers know something about preventive maintenance on a vehicle. We know we should routinely replace the oil and wiper blades and other fluids. But have you heard of a PCV valve ? This little car part needs to be replaced regularly or it can cause some serious problems in your vehicle engine.

PCV stands for Positive Crankcase Ventilation. The crankcase holds your motor oil and is located at the bottom of your engine.

When fuel is burned in your engine, it produces waste gases that are mostly vented out through your exhaust system. But some of these gases push their way past the pistons and into the crankcase. There, these gases can mix with motor oil to produce oil sludge, which can damage vehicle engine parts through corrosion and by clogging engine passages. Anchorage vehicle owners should be advised that if the engine is running at high speeds, these gases can also cause pressure inside the crankcase to build up. This pressure, in turn, can blow gaskets and damage seals, leading to oil leaks.

The waste gases that leave the engine are comprised of about 70% unburned fuel. They used to be vented off the crankcase into the atmosphere. But starting in 1964, laws mandated that these gases be recaptured. Manufacturers began installing PCV systems, which recycled the gases into the air intake system where they could be mixed with fuel and sent to the engine to be burned.

The PCV valve is a one-way valve attached to the crankcase. Waste gases exit the crankcase through the valve but cannot enter.

Over time, the waste gases leave deposits on the PCV valve that can gum it up. So it needs to be replaced occasionally. This is an inexpensive part of preventive maintenance that is often overlooked, but which can have very expensive consequences. It's good auto advice to keep this little valve clean and working well.

In order to maintain efficient circulation, the PCV system also has a breather tube that allows clean air to enter the crankcase. This air is usually filtered through the engine air filter. But some vehicles have a separate air filter for the breather tube called the breather element. If this is the case with your vehicle, proper maintenance of the PCV will include replacing this element. To find out whether your vehicle has this type of PCV system, check your owner's manual or ask your service advisor at L and M Motors Inc.

The PCV system reduces harmful vehicle emissions. The maintenance it requires is simple and inexpensive at L and M Motors Inc. A fouled or damaged PCV system can lead to serious engine damage for Anchorage drivers.

Let's all learn to practice good car care. It's good for our wallets, and it's good for our AK environment.

Hello Anchorage! Did you know that the first federally-mandated emissions control device was introduced in the 1960's? The Positive Crankcase Ventilation valve, or PCV valve, has been installed in AK vehicles since 1964 and represents the first legislation by the United States government to regulate harmful emissions as well as to improve performance in the country's vehicles.

The PCV valve, as you can probably guess, is located on the crankcase. The crankcase is the lowest part of a vehicle's engine. It houses the crankshaft and the engine oil. The crankshaft connects to the pistons that power the engine.

Pistons are pushed down when fuel is burned in an engine. This causes the crankshaft to rotate, which sends power to the transmission. It ultimately turns the axles and causes the vehicle to move. Some of the gases released by the burning fuel squeeze around the pistons and down into the crankcase.

If the escaped gases mix with the engine oil in the crankcase, oil sludge develops. This sludge has the consistency of petroleum jelly and can cause damage by clogging up passageways in the engine. Further, escaped gases can build up pressure inside the crankcase that can blow out seals and gaskets.

Before 1964, a hose was attached to the crankcase that vented escaped gases out into the air. These gases contained about 70% unburned fuel as well as harmful emissions. The PCV valve was designed to curb these harmful emissions as well as recapture unburned fuel.

The PCV valve is a small, one-way valve that allows escaped gases to exit the crankcase. The gases are then routed into the intake system so they can be re-burned in the engine. Fresh air enters the crankcase through a breather tube to facilitate this circulation and keep the air in the crankcase clean.

The PCV valve, like most working parts on a vehicle, will wear out over time. Usually it simply gets gummed up. Preventive maintenance, including routine oil changes at L and M Motors Inc in Anchorage, will extend the life of the valve, but eventually it will have to be replaced. A sticking PCV valve won't allow gases to circulate properly, which can increase pressure in the crankcase. Over time, that pressure will lead to oil leaks.

Your vehicle manufacturer recommends that a PCV valve be replaced every 20,000 to 50,000 miles (32,000 to 80,000 kilometers), depending on the vehicle and Anchorage driving conditions. It's an inexpensive repair but may not be included in the maintenance schedule in your owner's manual. So if you're looking for auto advice about the PCV valve, you may have to ask our pros at L and M Motors Inc.

Taking care of our PCV valve protects the environment in AK and improves vehicle performance. It's just part of good vehicle care for Anchorage drivers and a way all of us can do our part to improve the world we live in.

Anchorage drivers may feel intimidated when they take their vehicles to a service center. They have questions but aren't sure how to ask. They don't want to feel embarrassed about their lack of knowledge. They don't want to make the service technician feel that they don't trust him.

If your service advisor at L and M Motors Inc uses a term you don't understand, just ask him to explain. Remember, they are the auto service experts. If they came to your place of work, they probably wouldn't understand the jargon, either. When you take your vehicle in to be serviced, make sure you understand the financial issues up front. Ask about payment policies, warranties and, of course, the cost of the work being done.

It helps to understand basic services your vehicle needs. Know the difference between a quick check-up and a thorough inspection, which you are getting and which you are asking for. Understand that diagnosing a problem takes time, and time isn't free. If you have concerns about cost, negotiate your limits before service is done. Don't be afraid to ask your service advisor for auto advice on how to keep your vehicle on the road within your budget. He can help you prioritize your vehicle's needs. Some repairs are for the safety and future health of your vehicle. Others can wait. Your L and M Motors Inc service advisor can help you set up a plan to get all the work done as you can afford it.

It may be tempting for Anchorage drivers to save money with budget parts. Your service advisor can help you to sort through the options to work within your budget. High-quality parts are always preferable for any auto repair. Your service advisor will make sure the parts used won't compromise the safety of your vehicle.

Don't leave your Anchorage service center without your paperwork, either. Ask about warranties for parts and labor. You may need these for claims or if there is a problem in the future. Get detailed explanations of the work done on your vehicle. These records will help you keep track of repairs, service and warranties.

Those records may also help close a deal when it comes time to sell your vehicle. After all, the biggest concern most people in Anchorage have when buying a used vehicle is that they are inheriting someone else's problems.

Records of repairs and service are a good picture of your vehicle's condition and performance and what problems a new owner can expect. People are always happier to purchase a vehicle they know has been well-maintained. Whenever we climb into a vehicle, we are entrusting our health and safety to it. Perhaps it's time to take our vehicles' health a little more seriously. Open up; ask and learn.

Beware of Cheap Tires in Anchorage

Do you like to shop for shoes in Anchorage?When buying a running shoe, is quality important?Does durability matter as long as the shoes look fabulous?Would you rather have one pair of long lasting shoes or two pairs of lower quality shoes at the same price?

Is the warranty important when buying tires?

Anchorage drivers should also think about the safety aspect of tires. The tires do a lot of work – they carry the weight of the vehicle and you and your passengers. You want to be sure they hold the road and provide good traction on AK freeways and surface streets. If you carry heavy loads or tow a trailer on AK highways, the tires need a high load rating.

Ask your friendly and knowledgeable Anchorage tire professional at L and M Motors Inc. I think it's important that Anchorage residents understand the effect of price on a tire's quality, performance and durability. When I was a kid, my dad would say, “Pay twice as much and buy half as many.”

The same principle applies to tires. The major tire brands that you're familiar with in Anchorage are known as Tier 1 tires. These tires are high quality and well-engineered. Comparable vehicle Tier 1 tires are usually priced similarly.

Stepping down, you come to private label tires. Some large AK tire store chains carry tires with their own brand. It's important to know that most private label tires are built by the same Tier 1 companies that you are familiar with – so you are pretty safe in choosing them. To be sure, you can ask your L and M Motors Inc tire professional which manufacturer makes their private brand.

The lowest priced tires on the market in Anchorage are Tier 3 tires which are usually imported from China or South America. Since you get what you pay for, you can't expect a Tier 3 tire to deliver the same performance and durability as the others.

What's the difference in thetires with high mileage warranties? It's the rubber compounds and the amount of tread material. As you might expect, you'll pay more for the longer-lasting tire.

Your tires are the only parts of your vehicle that touch the road. You're only as safe as your tires are well built. Buy value – not price.

Give us a call.

Synthetic Oil for Anchorage Autos

Posted November 1, 2016 6:47 AM

If you are a driver in Anchorage and you aren't currently using synthetic motor oil in your vehicle, maybe now's the time to consider it. Need more information? Well, synthetic motor oil is a substitute for petroleum based oil.

Synthetic oil doesn't gel or gum-up like petroleum based oil and it doesn't vaporize as easily. It protects better in severe driving conditions like stop and go driving around Anchorage, as well as in very hot or very cold conditions. More and more new vehicles are being delivered with full synthetic motor oil, with the recommendation to use synthetic for the life of the vehicle.

Why is this? Synthetic motor oil maximizes engine power and fuel economy. To see why, we'd need a microscope, so we'll have to settle for using our imaginations.

The molecules of conventional motor oil are long hydrocarbon chains. Synthetic motor oil, on the other hand, has uniform, round molecules. Which is more slippery, a pile of pencils or a pile of marbles?

Synthetic motor oil lubricates better because there's less friction. That means better wear protection, cooler operating temperatures, more power and better fuel economy. And synthetic oil doesn't sludge up like conventional oil, so it prevents those small oil passages from clogging up.

Some manufacturers are extending oil change intervals. The added protection of synthetic oil covers you for these longer intervals. Talk with your service advisor about how you drive and see if he thinks you can benefit from synthetic oil. Also ask about the appropriate oil change interval for synthetic, because it may very well be longer than for conventional oil.

Most of us here in Anchorage have a busy life and might occasionally miss an oil change; go ahead, admit it. Since we're not perfect, doesn't it make sense to use a motor oil that's got your back?

Now synthetic oil costs more. But it lasts longer, protects better and increases fuel economy. You'll likely save money in the long run. If you're serious about making your car last longer, start using synthetic motor oil right away.
